Things are not getting much clearer for me
The example of Arti'z archive really gives me the idea that inlay and crowns have been combined on that piece.
As for the piece from Michael with the bone piece.
This is to me feels like a later restauration.
Ps. In the invincible Keris 2 there is mentioned that Suasa was higher appreciated than gold. Seems a bit unlikely to me. any ideas on that ?
